Abstract

La présente invention a trait à un insert de découpe qui inclut deux surfaces d'extrémité opposées et une surface latérale périphérique s'étendant entre les deux surfaces d'extrémité opposées. La surface latérale périphérique inclut deux surfaces latérales principales opposées qui sont reliées à deux surfaces latérales secondaires opposées par l'intermédiaire de surfaces latérales de coin. Un bord périphérique est formé à l'intersection de chaque surface d'extrémité avec la surface latérale périphérique. Chaque surface d'extrémité est dotée de deux coins surélevés dotés d'arêtes tranchantes de coin surélevé associées et de deux coins abaissés dotés d'arêtes tranchantes de coin abaissé associées. Chacune des surfaces latérales de coin inclut une dépression de dégagement concave qui tient lieu de surface en relief d'une arête tranchante de coin abaissé associée. La dépression de dégagement concave s'étend de son arête tranchante de coin abaissé associée dans la direction d'un coin surélevé, sans jamais le croiser, associé à la surface d'extrémité opposée.
